CONTRIVANCE FOR DIMINISHING THE DANGER T FOOT-PASSENGERS FROMSTREET-RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 519,91] dated May 15,1894.

To all whom it may concern.-

Be it known that we, FRANZ JERNETZ and FERDINAND JENICZEK, of Vienna,Austria- I-Iungary, have invented a new and useful Gontrivance forDiminishing the Danger to Foot-Passengers from Street-Railways, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

This invention relates to automatic guards or protectors for tram carsand similar vehicles to remove any person or obgect lying on or betweenthe rails or to prevent their being run over.

A guard or protector constructed according to this invention is normallyraised from the tector for use with smaller cars.

- ground but is automatically lowered into its operative position on theapproach of the car to any obstacle. After the obstacle has been removedthe guard or protector can be easily raised by the driver.

The accompanying drawings illustrate 1n what manner this invention maybe carried into efiect.

Figure 1 is a side elevation of the lower part of a car furnished withthe improved guard or protector. Fig. 2 illustrates it in end elevation.Fig. 3 is a plan of the guard or protector adapted for use with largecars. Fig. 4. illustrates a similar view of a guard or pro- Figs. 5, 6,7 and 8 are illustrations of details of the apparatus drawn to anenlarged scale, and Fig. 9 is a detail front elevation of amodification.

The apparatus consists essentially of two parts, the guard or protectorAand the actuating device 13. The guard A 1s ordinarily held up in theposition indicated by the dotted lines in Fig. 1 and is automaticallylowered into the position shown by the full lines when the actuating orindicating device B comes into contact with any obstacle. To allow ofthe desired movement the guard A is hinged or pivoted to the hangingplates p by means of bolts r. (Fig. 2.) The front end of the guard A issuspended by means of a link 6 from one end of a lever a the other endofwhich is connected at 0 to Vertically moving rods or bars I] whichpass up and through the floor of the car so that they can be depressedby the driver or conductor to raise the guard or protector. The lever ais pivoted in the lug g. The raised position of the guard is indicatedby the dotted lines in Fig. l.

The apparatus for maintaining the guard in its highest position isillustrated in Figs. 1, 2, 5, 6 and 8. Two suitable arms at are hingedto the bracket h secured to the car floor and are arranged to pass oneon each side of the lever a. Springs e are combined with the arms d andpress against pins z' so that the lower ends of the arms arecontinuously pressed forward. Each of the arms d is formed with a stepor projection which engages with a transverse pin or plate 0 secured tothe lever a and normally prevents its ascent and the consequent descentof the guard. A board or plate f preferably formed of wood, or a rollerf (Fig. 8) is secured to the lower ends of the arms 61 and has restingagainst it part of the actuating device 13. This actuating device Bconsists of a hinged plate or series of connected vertical rods pivotedin the brackets 70. The rods composing the series are suitably stayedand connected together and are held in position by means of the springmand the chain n. The height of the lower edge of the actuating devicefrom the rails and ground can be adjusted by means of the nuts Z.

The operation of the apparatus is as followsz lf, during the running ofthe car, the lower edge of the actuating device B comes into contactwith an object or person lying on the ground, then the device B is movedbackward carrying the arms 0? with it as shown in the full lines Fig. 1.The steps on the arms d are thus moved outof engagement with theprojections c and the guard A is free to descend to the operativeposition. The extent of thedescent of the guard A may be limited byastopcombined with the lever, or, and preferably, by a small wheel or wheelsa which come into contact with the ground or rails. After the obstaclehas been removed the driver restores the guard to its original positionby depressing the rods 1) with his foot, thus lowering the front end ofthe lever on and raising the guard duplicated, one set being placed oneach end of the car so as to be available for use in Whatever directionthe car is running. The apparatus at the rear of the car may be locked 5in its inoperative position by means of the cranked rod furnished with afolding handle y and mounted so as to rotate in the eyes or rings 2'.

For greater safety and to prevent the poszo sibility of any personbecoming entangled with the actuating device B it may be constructed asshown in Fig. 9 and covered With wire gauze or similar material.

The positions of the various parts of the apparatus when the guard is inits lowest position are indicated in Fig. 1 by full lines.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is

1. An automatic guard for. railway, tram cars and similar vehicles,consisting of the hinged vertically moving shield A suspended by thelever a which carries the pins or plates 0, the catch bars 61 capable ofengaging with the pins or plates 0 and furnished with the railf, springse engaging with the catch bars d, vertically moving rods 1) attached tothe lever a, and furnished with a foot plate, and a hinged plate orframe B substantially as set forth.

2. In an automatic guard for cars, the lever arranged to support themovable shield, spring-controlled catches arranged to press upon thelever and hold the shield in inoperative postion, and means fordisengaging the catches upon approaching an obstacle; substantially asdescribed.

3. In an automatic guard for railway and tram cars and similar vehicles,a lever a from one end of which the shield A is suspended the other endbeing furnished with the projections c and the rodsb carrying afootplate, substantially as set forth.

In Witness whereof We have hereunto set our hands in presence of twowitnesses.
